We now know what caused the carbon monoxide leak at a Roanoke College fraternity house.
Fire officials tied the leak to a clogged flue pipe in the boiler system. The students returned to the house Saturday night.
Newly-installed carbon monoxide detectors may have saved the lives of some Roanoke College Students. Detectors warned them of a carbon monoxide leak overnight at the Sigma Chi fraternity house on campus.
